Overactive Bladder- medicine hasn't affected symptoms, what can I do?

I'm a teenager in secondary school and I'm unable to hold urine for over an hour at the best of times. Trying to sit through classes is impossible. I also suffer from the inability to hold in wind as a result of the pressure of my overactive bladder. I suffer regularly from utis and as a result my bladder is severely overactive. I've tried all the medicines and herbal remedies and I'm not willing to go down the Botox route as the cons outweigh the pros for me. Any other options would be greatly appreciated.
